If you choose not to stake the plant, what horticultural reason might exist to still prune straggly vines?
Answer
To keep the plant looking tidy while allowing a natural trailing display.
If the desired display is trailing, staking is unnecessary, but pruning unruly or unhealthy stems helps maintain a neat appearance without forcing an unnatural vertical posture.
